The AmeriGlo I-Dot Sight Set in black (AmeriGlo part no. GL-205) is built for the same slim single-stack Glock 42, 43, 43X, and 48 lineup as AmeriGlo’s Agent 3-Dot set, but uses AmeriGlo’s I-Dot sight picture instead of a traditional 3-dot pattern. The I-Dot design uses a vertical bar or elongated front reference rather than a simple round dot, a configuration some shooters find easier to align quickly and consistently under stress. Paired with a square notch rear, this set is a direct swap for the factory sights on any of the four compatible slim-frame Glock models.
